Be it known that I, Pnnnnz ALLEN CLARK, of Anaheim, county of Los Angeles, and State of California, have invented an Improved Quadruple Suction and Force Pump; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawings.

4 My invention relates to a novel construction for pumps; and it consists of a rocking or oscillating piston moving upon a longitudinal axis in a cylinder which has a diaphragm This diabe made with open ends, having suitably-secured heads, but I prefer to cast my cylinder in two parts having flanges, so that the cylinder may be secured by these flanges 'in the center, while the ends are made solid or cast with the cylinder, and they may be curved or rounded in shape. Horizontally i across the cylinder'(which I have shown lying on its side) I form a partition or double diaphragm, B, extending' from end to end, and this dia phragm has double sides, so that it furnishes water-passages, and also a space for the operation of double-acting valves.

The piston consists of a rectangplar plate, G, mounted upon a shaft, D, which extends longitudinally through the axis of the cylinder, and rotates or oscillates in a packed joint just at the meeting edges of the two parts of which the `diaphragm B is formed. The piston also has its edges suitably packed, and one half of it works below the diaphragm, while the other half moves above it, being caused to oscillate from side to side by the movement of the axis or shaft D.

The two parts of the diaphragm B are eac provided with apartition midway between their ends, so that they are divided into four chambers. Each of these chambers is provided with a double-acting valve, two of these valves being suction and two discharge valves. The suction-valves are composed of two disks, E E, one above and one below the diaphragm, these disks being united by a stem, F, and closing the upper and lower parts alternately from the outside. A passage, Gr, is formed preferably upon the outside of the cylinder, as shown, and extends Jfrom the suction-pipe H up on each side of the cylinder, -so as to open into the space between the sides of the diaphragm upon each side of the piston.

It will now be'seen that at each movement of the piston water will be drawn into the cylinder above one-half of the diaphragm through the upper half of the valve E E, and also into the portion of the cylinder which is diagonally opposite, through the lower half of the valve upon that side. The opposite halves of each valve will, of course, close the other sides of the cylinder.

The discharge-valves in each half consist of single disks I, with stems J, by which they are guided, and these valves work inthe interior of the space within the diaphragm, so as to alternately close each upper and lower port from the inside. This portion of the space within the diaphragm is connected with the exhaust-pipe K by means of passages L, similar to those at G.

The operation of each valve is to close first nally opposite will be taking in water while the other two are discharging it.4

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, Ais- 1. The cylinderA, withits double diaphragm I B and double-acting ingress and egress valves E and I, in combination with the piston C,

mounted upon the longitudinal shaft so as to oscillate in theol-chambers upon -Aeach side of the. ediaphragm, substantially' `as `and for .the

purpose herein described.

2. The double ingress-valve composed of the disks E E, united by the stem F, and operating alternately upon the outside of openings in the double diaphragm B, substantially as and.

for the purpose herein described.

3. The discharge-valued, Working vWithin the diaphragm, so as to alternately close the upper and lower discharge-opening, substantiallyfas herein described.

4. The cylinder A, constructed with fthe:

semicircular passages G and L, communicating respectively With the ingress-pipe and the suction-chambers in the diaphragm, and with constructed .as to lperformtheir duty in both directions, substantially as herein described. In witness whereof -I have hereunto set my l. 4hand and seal.
